ABLIC Inc. launched the 2-wire serial EEPROM S-34TS04L with temperature sensor which operates in 1.7 V to 3.6 V voltage ranges. This IC has the capacity of 4 K-bit and the organization of 2 pages × 256-word × 8-bit. Page write and sequential read are available.
This IC operates with the I2C-bus at 1.0 MHz maximum.
A substantial reduction in current consumption may be achieved by using the software programmed shutdown mode which can be set by the I2C-bus.
In addition, the SMBus timeout function is supported; therefore, this IC is optimal for SSDs that communicate over the SMBus.
